Well, I've been working through the trouble shooting from the very helpful thread https://endless-sphere.com/forums/viewtopic.php?f=2&t=764&start=25 In that thread there a picture that matches by board https://endless-sphere.com/forums/posting.php?mode=quote&f=2&p=93844...

I've been reading multiple thread but could not find one that suggests anything I have not already tried. I have a Crystalyte 4012/409 hub and a controller for it. As a dual winding hub, the controller has a switch to determine which of the two windings it will use so its not built into the...

Well with a good bit more searching I still did not anything about the unknown 361A chip, so ordered a different model of BMS to replace it. Still hoping I can fix this as a backup so any tips/ideas welcome. Anyone with an old dead BMS with that part on it they want to get rid of I'll cover...

My BMS has failed (and took a headway cell with it). There was a broken sense wire as well so not sure if that cause it or happened when I disassembled the pack. Normally I plug the bike in every day (its my daily commuter). The bike was working fine before vacation but I left it unplugged...

After a long of diagnosis I believe the LED are more than just a volt-meter and that the red-green combination was indeed a sign of LVC. The battery was fine, and I had been reading the status from leads connected to the battery which is why I though it could not be LVC as the battery showed...

Oh thanks, but I would not care about the LEDs... The issue is that when it is in the red/green state the bike does not work at all. So I wondered what it is trying to tell me. Rode it into work and it seemed okay. But as I headed home, it happened again. I ended up opening up my plastic...

I have an bike kit I bought on craigslist. Have it hooked up and running but last week it cut out and the "three leds" (red=low, yellow=medium, green = high) showed only red and green (i.e. skipping medium) Does anyone have an idea what that indicates? Turning on/off did not reset, but...

Just build a home made pack from recycled cells from some military batteries I had laying around. A mix of two types, I tried to balance the capacities in my strings while also trying to keep the original pre welded groups for stability. Then I soldered 12gauge wire connecting them. I got...

Thanks for the feedback. Well I got some time to disassemble the controller.. and alas the caps are 50v, so no easy upgrade. Pic below So for the record.. a HuayuxinFeng machinery & electron co controller model XF1011090121 is not upgradeable to 48v... (added incase someone else goes...

I bought a used e-bike kit on craigslist. is 36v ampedbike kit with bottle battery. The Battery is toast.. I'll disassemble to see what cells I can reuse. and test the BMS. I won't use the bottle, and have lots of 18650s to build a new battery for my older lashout, which has a nice battery...

sorry for the delayed response.. been a while sinceI logged on as the new build has been relatively trouble free. Only logged on as Im looking at a used motor for a second build -- the old lashout as eaten 2 more gears when being used by a lightweight friend, so I've decided that design is...

Thanks.. going back would be a good bit of work and I'll then have no brakes, so I've been trying to avoid that. Not sure what you refer to as the axel shoulder. Here a pic of the inside of the old cover, where the bearings went. In the old cover the bearings were close enough to the...

Thanks dan.. the axel on the gear side has a nice shoulder and it is sitting nicely. On the side where the wires come out of the motor there is no shoulder, there the threaded axle with washers. I took it all apart and reassembled it again today. Here is the original ordering It has two...

How much friction should there be in a hub? I know direct drive has more inherent friction, but I think my hub now has more than normal. Contact: I bough a used Crystallite 4012/4009 hub and build a bike around it. My original build thread has pic...

I did a flashlight for a while.. but always worried about it being stolen and when I forgot to charge it and it was almost dead and I had to ride home in the dark I went for a dual cree light from eBay as my headlight. Been using it 2 years and would never go back. I only went for 500LM and...
